DANIEL AGGER is stepping up his quest to return to full fitness – with the aid of a special pair of boots.

The Danish international has been out of action with an ongoing metatarsal problem since September with the injury proving more difficult to correct than had originally been thought.

Earlier this month he suffered the disappointment of seeing a planned comeback aborted because he felt more discomfort in his foot during training.

Since then, Agger has been to see a foot specialist in Spain and has been working with boot manufacturers Adidas in a bid to find a solution to the problem.

And yesterday he made his return to training wearing a special pair of boots and manager Rafa Benitez is hopeful of having Agger back in his first team squad soon.

“Daniel is back in training which is very good news for us,” said Benitez.

“Everyone has been working very hard to find a solution to his problem and he now has a new pair of boots which we hope will make a difference.

“They have been made especially for him by Adidas and they are different from normal boots because they take some of the pressure off the metatarsal that is causing Daniel the problem when he is kicking the ball.

“It would be very good for us if Daniel can prove his fitness because he has become a very important player for us.”

Meanwhile, Momo Sissoko has written a letter to the Liverpool fans thanking them for the support they gave him during his two year stint at Anfield.

Earlier this week, the Mali international moved to Juventus in a £9m deal and Sissoko admits leaving the Reds has saddened him.

He said: “As soon as I arrived in Liverpool I realised how much this team meant.

“Now, after two and a half years I have to say goodbye and I can’t hide the great sorrow I feel in leaving one of the best clubs in Europe.

“Liverpool FC as a club, its fans, its coaches and my team-mates have together helped me to become a better player and, above all, a better person.

“Liverpool FC is one of the greatest. The Liverpool fans never desert their team.

“Even in the worst moments you have a strong sense that the fans are with you, supporting you as much as they can, never giving up, those fans make Liverpool even stronger.

“I really want to thank them for helping me to feel and to understand what football means in its purest form.

“I also think Liverpool FC functions this way because of its leaders – Rafael Benitez works from dawn to dusk, and the players know they must fight for the red shirt in every second of every match.

“Now I am beginning a new adventure in another big European club in Juventus. They have put their faith in me.

“I shall play to my best in every match, I shall fight hard for my new shirt to the end, but when every match is finished, I know what I’ll do first – I shall ask about the results of Liverpool FC.

“Everybody knows the legend “You’ll Never Walk Alone” and I shall never, ever forget the experience and the team.”
